Patented Jan. 23, 1951 UNITED STATES PATENT OFFICE 7 Claims. (Cl. 189-69) This invention relates to metallic windows and more particularly to the construction of the swinging type of window ordinarily employed in factorles.

An important object of the invention is the provision of a'structure which lends itself readily to mass production and in which the component parts may be produced in the form of extended strips which are subsequently divided and assembled to form windows of the desired size and form.-

Another and importan object of the invention is the provision of a window composed of elements which may be produced from certain metals such as aluminum by extrusion methods and which, accordingly, may be very cheaply manufactured.

Another object of the invention is the provision of a construction enabling a cheap and eflicient screening of the window.

Another object of the invention is the provision of a window which may be very readily installed in or removed from its frame.

Another object of the invention is the provision of a structure which readily lends itself to weather stripping.

These and other objects I attain by the construction shown in the accompanying drawings wherein for the purpose of illustration I have shown a preferred embodiment of my invention and wherein: h

Fig. 1 is an elevation of a completed window constructed in accordance with my invention;

Fig. 2 is an enlarged vertical sectional viey therethrough;

Fig. 3 is an enlarged fragmentary elevation thereof, the outer screen unit being removed;

Fig. 4 is a section on line 44 of Fig. 3;

Fig. 5 is a section on line 5--5 of Fig. 2;

Fig. 6 is a section on line 6-6 of Fig. 4;

Fig. 'l is a combined perspective view of the hinge mounting and brake;

Fig. 8 is a section on line 88 of Fig. 2;

Fig. 9 is an exploded view showing the various elements of the window prior to assembly thereof; and

Fig. 10 is a section on line l0l0 of Fig. 9.

Referring now more particularly to the drawings, the numeral I0 generally designates a main frame member substantially U-shaped in cross section and adapted to receive between the flanges l2 thereof the wall elements 13 of the wall in which it is mounted. The outer face of the base H of the U has spaced ribs I5, adjacent faces of which have opposed longitudinal slots IS, the

purpose of which will presently appear. The inher face of the base of the U is grooved as at l1 for the reception of auxiliary frame elements or stop strips I8. Stop strips l8 are substantially L-shaped in cross section, the outer face of one arm of the L being longitudinally ribbed as at I9 with ribs adapted for press fitting into the grooves ll of the main frame Ill. The grooves ll of member H) are preferabl formed in a ridge element 20 arising from an otherwise flat ledge 2|.

The sash 22 comprisesa transverse member or parting bar 23 circular in cross section and having diametrically opposed glazing grooves 24. This member further has a polygonal axial opening 25 extending entirel therethrough and may, as shown, be provided with longitudinal voids 26 to further reduce the weight thereof. The sash frame members 21 each comprise a longitudinally cavital bar, the cavity of which is designated at 28 and serves both to lighten the bar and to provide for the reception of means for maintaining the bars in assembled relation as will hereinafter more fully appear. The outer faces of these bars are provided with opposed flanges 29, one of which has at its inner face a rib 30 and the other of which has at its inner face a pair of ribs 3| and 32. The rib 30 is well spaced from the bar 21 proper and confined between this rib and the bar is the base W of a U-shaped weather strip; the inner arm 33 of which has its free end confined between the rib 3| and the bar and the other arm 34 of which is flexed outwardly so that it projects beyond the outer ribs 29. The free end of this arm is disposed between ribs 3| and 32 which are spaced to permit a free flexing of said arm. The weather strip is composed of any suitable spring material, such for example as spring bronze, and in common. with the remaining elements previously described is formed as a continuous strip. The inner faces of bars 21 are provided with a glazing groove 35.

It will be obvious that each of the elements hereinbefore described is capable of mass production by either an extrusion process as in the case of the main and auxiliary frame members it) and I8, the parting strip 23 and the sash frame bars 21, or by rolling as in the case of the weather stripping. In the construction of a sash from these elements, the frame is assembled by combining the main and auxiliary frame elements forcing the ribs I!) of the auxiliar elements into the grooves I! of the inner face of the main elements. In the construction of a window of the type illustrated in the present drawings, assembly of these elements for formation of the top and with one another, a high friction ratio.

bottom rails of the frame may be made for the full, length of the strips as produced and the strips subsequently divided into sections of desired length. In constructing the side rails, two sections of the auxiliary strip are assembled upon a section of the main sash member, these sections being reversed with relation to one another so that the stop flanges 86 are arranged at opposite sides of the centers thereof. The main strip is then milled out as at 31 for the reception of a combined pivot bearing and brake element 38. This element preferably comprises a die casting 39 having a pivot-receiving opening 40 formed therein and having a segmental recess 4!, the outer wall of which is concentric with the opening 40. It is further provided with a stop lug 42 having a face 43 to engage and check movement of the sash at fully open position. This lug and openings 45 for the reception of securing elements for attaching the casting to the frame is preferably formed on an extension to that side of opening 40 having the recess and the casting is attached to the frame with this side thereof arranged at what is to be the inner side of the window when placed in position. Arranged within the recess 4| is a segmental brake block 46, the central portion of which is notched at 41 to fit the pivot hereinafter to be described and the periphery of which is engaged by a set screw 48 serving as a, means to regulate the flexible engagement between the block and pivot. The said extension of the casting 39 is made such that the securing elements S are accessible when the window is in closed position.

Assembly of the top and side elements of the frame is effected by means of angle brackets 480 which have a driving fit in the slots IS. A very secure connection of these elements and proper alignment thereof is thus provided particularly where the metals employed in the construction of the frame elements and of the angle members 48a are dissimilar metals having, in engagement In the assembly of the sash, a section of the parting bar 23 of proper length is provided and the ends of this section are diametrically slotted as at 49 to receive the side sash frame members 21. These side frame members are secured in position in the slots by pivot elements 50, more particularly shown in Fig. 4. Each pivot element comprises a tang of a size to have a driving fit in the axial cavity 25 of parting bar 23, an enlarged portion 52 to have a driving fit in a bore 53 formed in the side members of the sash frame and a further enlarged pivot head 54 adapted to engage in the pivot opening 40 of bearing casting 39 and to be engaged by the brake segment 46. Assembly of the side and end members of the sash frame is accomplished by angle brackets 55 which are constructed to fit in the cavities 28 of the sash frame bars.

It will be obvious that insertion and removal of the sash in a window of this construction is an extremely simple operation. In inserting the sash, for example, the bearing castings may be placed upon the pivots 54 and through the set screws 48 frictionally engaged therewith toan extent sufficient to hold them in a desired position. The sash with these castings thereon may then be placed in the frame rotated to its closed position and the securing elements S for the bearing castings placed in position. It will also be obvious that a construction of this character readily lends itself to screening. As at present shown, upper and lower screen sections ii are secured against the stop flanges 38 by pins l1 and releasable spring snaps "an The adjacent ends 'of the screen sections have their framing elements ll shaped to conform to the circular body of the parting bar and will accordingly provide a substantial closure with the parting bar in all positions of the window. It will thus be obvious that the structure may be very readily and cheaply manufactured and installed and will, at

the same time, provide a window having all of the advantages now in common use.

Since the specific formation of the various elements as illustrated is obviously capable of considerable modification without departing from the spirit of my invention, I do not wish to limit myself thereto except as hereinafter claimed.
